The reopening of First Park wasn’t the only thing washed out on Earth Day. The rain also put a damper on the Polar Bear Bike Ride, an annual fete organized by East Village-based organization Time’s Up. Lucky for us, it was rescheduled and took place yesterday in Union Square. The group has a knack for decorating bikes to send a message – as you can see from our slideshow it was on full display at the event, meant to encourage others to reduce their carbon footprint by cycling.
